There are a LOT of things that are different about traveling to Walt Disney World right now. You need a Disney Park Pass reservation to even get INTO a theme park, there are very few live shows, character flotillas and cavalcades have replaced traditional meet-and-greets, and so on… .
A LOT of these changes you can plan for well in advance of your trip. You can reserve Park Passes as soon as you know you’re going to Disney World (subject to availability, of course), you can pack extra masks and hand sanitizer to prepare for enhanced health and safety measures, and you can temper expectations knowing you may not get to do EVERYTHING you were once able to enjoy at Disney World.
